A search for Threads content on Twitter currently brings up zero results, despite plenty of links to Meta’s microblogging rival being posted on the platform.
My gut reaction is defensiveness that the fediverse has a different motive, but no. The motive IS the same. Both are fueled by self-preservation.
There IS a difference in circumstance, however. The fediverse has to measure potential gain vs potential risk of working with a greedy rich billionaire.
Twitter is already a giant that’s been going through a lot of abuse and bleeding users. It stands to gain nothing from Meta’ new copycat, only lose even more.
So, Yes. Same motivation for blocking/defederating. The difference between the two is what thy stand to gain vs what they risk losing.
